Product Summary

A rubber gate valve is a kind of gate valve made from rubber material. The construction of a gate valve is quite simple. They generally have two threaded connectors that hook into the pipe system. It is possible for a gate connector to have more than two connections, but this is very rare. A post, called a bonnet, rises above the connectors; this area holds the stopping wedge and the mechanism for raising and lowering it. Lastly, a handle, which controls the rising and lowering of the stopper, sits on top of the bonnet.

When the handle is turned, it moves the stopper inside the valve. The stopper slides down into the pipe and blocks liquid from passing. The valve will typically indicate the position of the stopper on the outside of the valve, or the handle will screw in and out to show the relative height of the stopper. The valve casing is slightly wider than the connected pipes, allowing the stopper to totally cover the opening and make it completely liquid-tight.
